This happens to my machine on a semi-regular basis, basically, when the computer is left running for several days unattended; that is, I don't login, ttyv0 ends up "hanging". It no longer responds to keypresses or "kill -KILL" attempts. In the past, I have to reboot the computer to get rid of this process. I have never seen any other virtual terminal exibit this behavior; only ttyv0. Here is some output from ps: USER PID PPID PGID SESS JOBC STAT TT TIME COMMAND root 18274 1 18274 7aace0 0 I<Es+ v0- 0:00.00 (login) According to the manpage, this process is idling, not surprising as I haven't done anything with that terminal all night... Has "raised CPU scheduling".. no clue there.. it seems that no other processes are listed as having increased service rates. "E", denoting that the process is trying to exit.. no doubt from the kill -KILL I sent it when it stopped responding. "s", denoting that the process is a session leader, and finally the "+" showing that the process is the forground group. top had this information to provide on this process: PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 18274 root 4 -4 184K 228K ttywai 0:00 0.00% 0.00% login I am using: FreeBSD 2.2.6-BETA FreeBSD 2.2.6-BETA #0: Sun Mar 22 22:44:22 EST 1998 Has anyone experienced anything similar, or perhaps have a suggestion on how to clear up this behavior? -d To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
